VALVE.

Application filed may 16, 1921. Serial No. 469,934.

To all wwm it may cmcem:

Be it known that I, EUGENE A. STILES, a citizen of the United States ofAmerica, residing at Kokomo, in the County of Howard and btate ofIndiana, have invented certain new and usefui Improvements in Valves, ofwhich the following isa specification, reference being had therein tothe accompanying drawings.

This invention reiates to valves for controlling the fuel Supply 'ofautomotive Vehicles.

It has for its object the provision of a fuel control means, whereby anormal fuel supplyor an auxiliary fuel Supply may be obtained -from aCommon Supply tank, or a complete closure made by the use of a singlevalve.

A further object of the invention is to provide a screen and settlingChamber 10 to collect any dirt and water that may be in the fuel and toprovide means permitting this foreign matter to be removed from thedevice. A

A further object of the device is to provide a controlrrod and aConstruction permitting its ready adaptation to cars requiring differentlengths due to the different distances from the fuel tank to the pointof control.

With the above and other objeots which will appear more fully in thespecification, the invention consiste in the parts and combinationsthereof and, the mode of operations or their equivalente as hereinafterdescribed' and set forth in the claim.

In the drawing,

Figure 1 is a longitudinai vertical sectional view of the valve and aportion of the bottom of the fuel tank;

Fig. 2 is a side elevation taken at right angles to Fig. 1;

Figs. 3 and 4 are fragmentary sections showing the plug in 'difi'erentpositions of adjustment from that shown in Fig. 1 and Fi 5 and 6 areside and end views respectwely of the control rod.

y The valve consists of a body 1 having at its lower end a fuel Chamber2 with an opening in the bottom, screw threaded to receive a cap nut 3adapted to form a tight joint with the member 2 by the aid of a gasket4. The upper end of the fuel Chamber 2 has a recess 5 and the upper endof the cap nut 3 has a recess 6, the recesses 5 and 6 being adapted toreceive the ends of a shell-like metal frame 7 which supports a finemesh screen 8. The recesses, frame and screen will preferably becylindrical, though any other suitable form may be used.

In the lower end of the cap nut is a central bore 9 having a side outlet10, the bore 9 at its lower end being internally screw threaded toreceive a screw 11 having a tapered point adapted to close the outlet.

The upper end of the valve body 1 may be attached to the bottom of thefuel Supply tank in any suitable manner, a preferred form of attachment,shown in Fig. 1, comprising an apertured plate 12 Secured as by rivetinto the bottom 13 of the fuel Supply tank, t e plate being screw threadedto receive the threaded end 14 of the body.

The upper end ofthe body has two passages 15 and 16 in each of which isSecured a tube. One tube 17 terminates slightly above the bottom of thetank thus preventing scale or other heavy dirt from flowing with thefuel through the 'va1ve. The other tube 18 extende asufiicient distanceabove the bottom of the tank, that when all of the liquid fuel in thetank above the top of this tube 18 has been used, an emergency Supply offuel will still remain in the tank, which may be withdrawn through theshorter tube 17 by proper adjustment of the Valve plug 19.

The tapering plug 19 is provided with four porte. Two of the ports 20and 21, as

shown in Fig. 4 are in line with each other,

so that When the plug is set in the position shown in F ig. 4, the tube17 and passage 16 are connected directly by the orts 20 and 21 with theshort passage 22 below the plug in the body 1 of the valve. This passage22 opens into the interior of the screen 8. A delivery tube 23 isSecured by any suitable connection 24 to the side of the body 1, theOpening 25 being formed* in the side wall of the chamber 2 outside ofthe screen so that the fuel in passing from the tank through the valveto the delivery tube 23 must pass through the screen 8.

The piug 19 has two other ports 26 and 27 which are ofiset from eachother by a distance equal to the space between the passages 15 and 16 sothat when the valve is in the position shown in Fig. 1, the -port 27 isin line with the passage 15 and the port 26 is in line with the message22. The porte 26 and 27 are in communication as shown at 28.

Under normal conditions, the valve will be set in the position shown inFig. 1 so that the fuel in the tank above the top of the tube 18 mayflow through the passage 15, ports 27 and 26 and passage 22 into theinterior of the screen 8, thence through the screen 8 and the outlet 25into the tube 23 leading to the carbureter.

When the fuel has been exhausted down to the tube 18 the valve is turnedinto the position shown in Fig. 4, whereupon the fuel,

remaining in the tank above the level of the top of the tube 17 may beused as an emergency Supply. If the plug 19 is turned into the positionshown in Fig. 3, the passage 22 will be closed and the fuel Supply thuscompletely cut ofi'. The tapering plug 19 may be held in its seat by aspring 29 shown in F ig. 1 as bearing against a washer 30 on the body 1and at its other end against a Washer 31 held in place by a pin 32.

As a convenient means for controlling-the valve plug 19, I provide acontrol rod 33 adapted to be Secured within a socket 34: in the end ofthe plug 19 and extending to any oonvenient point that will 'be easy ofaccess. This control rod is preferably flatened on one side and drilledat intervals at 35 approximately at the length required for each type ofcar. These holes are so positioned that one will be in proper locationand the eXcess length of rod may be cut off and the hole used for acotter pin connec- -tion to the plug. This avoids the necessity ofdrilling holes when the device is to be installed.

As shown in Fig. 2, an indicating disk 36 may be Secured to the end ofthe rod 33, the disk having appropriate marks thereon to indicate theproper positions for various conditions of adjustment.

Dirt or water passing down into the center of the screen 8 will settlein the chamber and the dirt will remain in the bottom of this screen.Only clean fuel will pass through the screen into the fuel Chamber. TheChamber will be large enough to hold all the water likely to be found inthe fuel. From time to time the drain passage 10 may be opened or whennecessary the cap nut' 3 may be unscrewed so that the screen 8 mayatisse be cleaned and the interior of the chamber O 2 wiped out.

From the above description, it will be obvious that there is thusprovided a device of the character described possessing the particularfeatures of advantage before.

enumerated as desirable, but which obviously is susceptible ofmodification in its form, proportion, details of Construction, andarrangement of parts, without departure from the principles involved orsacrificing any of the advantages of this invention.

While in order to comply with the statute the invention has beendescribed in language more or less specific as to structural features,it is to be understood that the invention is not limited to the specificdetails shown, but that the means and construction herein disclosedcomprise but one of body having at one end thereof two longitudinalpassages arranged substantially parallel and spaced from each other, andhaving at the other end a Chamber provided with a cap nut, the cap nutand the opposite end of the chamber having co-operating recesses toreceive and hold in position therebetween a screen member, the cap nuthaving a discharge passage Communicating with the lower end of theinterior of the screen member and having a closure for the dischargeOpening, the chamber having an outlet tube adjacent to its upper end andoutside of the screen member, and the said plug having ports therein forestablishing Communication interchangeably between the two parallelpassages and the interior of the screen member.

In testimony Whereof I aflix my signa*- ture 1n presence of twowitnes'ses;
